Answer:
- have high melting and boiling points
- are hard
- are good conductors of electricity when dissolved in water
Explanation:
Ionic compounds are compounds that are formed between a metal and non-metal with a significant electronegativity difference. The metals transfers their electrons to the non-metals and the electrostatic attraction of the ions brings about the bonding that forms the compound.
Ionic compounds are diverse in nature and form.
Here are some of their properties:
- They are usually hard solids with a high melting point or liquids with high boiling points
- They are soluble in water and non-soluble in non-polar solvents
- They are able to conduct electricity in molten form.
- They undergo very fast reaction in aqueous solutions.
Answer: 0.004 moles
Explanation:
Amount of substance= mass/ molar mass
Mass= 250mg or 0.25g
Molar mass= 58.44gmol-1
Amount= 0.25/58.44
= 0.004 moles
